v WEATHER-STRIP.

Specification of Letters Patent. Patented Jun 22, 1920.

Application filed February 24, 1919. Serial No. 278,622.

To all whom it may concern:

Be it known that I, EDWARD J. CRAIG, a citizen of the United States, residing at lVest View, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification. Y

My invention consists of an improvement in weather strips, and has for its object to provide means for making a weather tight seal in connection with casement windows, swinging doors, and the like.

Generally stated, the device consists of a main bar or member of box-like formation in cross-section, having a middle open, trough-like body portion, provided at one side with a retaining flange or lip, and at the other with a receiving groove, adapted to be mounted upon a door or window sill and to cooperate with a relatively movable swinging door or window, having a coacting interfitting member thereon.

Preferred constructions of the invention are illustrated in the accompanying drawing, in which:

Figure 1 is a partial vertical sectional view through a casement window and frame provided with my improved weather strip.

Fig. 2 is a perspective detail View of the stationary or frame member.

Fi 3 is a similar view of the movable mem er.

Fig. 4; is a sectional view showing a modified construction. I

Referring to the drawings, 2 represents the sill portion of a window frame and 3 is the sash member of a casement window, of well known construction. The main stationary weather strip frame member is secured by screws or nails 1 extending downwardly through the bottom 5 of the strip, at each side of which respectively extend vertical side members 6 and 7, providing between them an intervening box or troughlike cavity 8.

The upper edge portion of wall 6 is turned inwardly, providing a terminal flange or lip 9, and the upper edge portion of opposite wall 7- is providedwith a receiving groove for the interfitting sash member strip. Said groove is formed by extending the comparatively thin metal of wall 7 outwardly at right angles thereto to form a lower horizontal ortion 10 which is reversed upon itself y a rounded bend 11 and extends backwardly, forming an upper wall 12.

The inner edge of the upper wall terminates at about the plane of vertical wall 7, and a space is thus provided between lower wall 10 and upper wall 12 for interfitting engagement by the sash member strip. The inner corner portion of the frame member strip is provided at intervals with outlet openings 13 for the escape ofmoisture, which may flow outwardly to the exterior of the building.

The sash member strip, of suitable thin metal consists of a securing flange 14: which is laid along the outer lower edge portion of sash 3 and is secured thereto by screws or nails 15, extending through suitable apertures. An outwardly extending rib portion 16, at right angles to securing flange 14; and preferably doubled upon itself, provides a double-thickness sealing rib, having an outer rounded edge, adapted to snugly interfit between wallslO and 12 of the frame strip, when the door or window is closed, as inFig. 1. I

'A coping 17 is also preferably mounted along the outer face of the sash as shown, projecting over or partly around the interfitting strip members, soas to partly protect relatively thin material from which the frame member is formed, the wall .6 and flange 9 will be resilient or have a slight spring action so that a tight contact will be had between these parts and the rabbeted portion of the sash 3.

If desired, he frame strip may also be made in the manner shown in Fig. 4, having the securing flange 1 1 with the doubled rib 16 extending at right angles thereto, but with the redoubled portion thereof at the lower side, extending rearwardly sufliciently far to provide an additional securing flange 18 for attachment to the under face of the rabbeted portion of the sash 3, by screws or nails as will be clearly understood.

With either construction, the interfitting strip, when closed, provides a practically tight weather-prom joint, effectually excluding rain, snow, air, dust, etc. The frame member itself is of strong substantial construction by reason of the vertical side members, and the inwardly extending flange 9 tends to retain any incoming matter, moisture, and to assist in preventing its movement inwardly through the window opening, from cavity 8.

The seep holes 13 readily eliminate any acccumulated moisture, and the compound strip, either when together in closed position or as to its individual members when separated, are equally effective in retaining their original shape or formation, under the ordinary usage of the device.

It will be understood that the proportions of the strip members, or their particular construction, as well as other detailed features may be changed or varied by the skilled mechanic without departure from the scope of the invention, but that all such changes are to be considered as included within the following claims.

lVhat I claim is:

1. A weather strip member consisting of a central bottom portion, a laterally extending wall portion at one side thereof, a second laterally extending wall portion at the opposite side or the bottom portion and projecting in the same'direction as the first wall portion, a receiving groove carried by the second wall portion, the opening of said groove being disposed toward the first wall portion.

2. A weather strip member consisting of a central bottom portion, a laterally extend ing wall portion at one side thereof, a second late "ally extending wall portion at the opposite side of the bottom portion and projecting in the same direction as the first wall portion, a receiving groove carried by the second wall portion and positioned to the opposite side thereof from the first wall portion, the opening of said groove being disposed toward said first wall portion.

A weather strip member consisting of a central bottom portion, a laterally extending wall portion at one side thereof, a see ond laterally extending wall portion at the opposite side of the bottom portion and pie j ecting in the same direction as the first wall portion, a flange extending, from the first wall portiontoward the second wall portion, and a receiving groove carried by the second wall portion, the opening of said groove being disposed toward the first wall portion.

4. A weather strip member consisting of a central bottom portion, a laterally extending wall portion at oneside thereof, said wall portion being flexible and resilient and forming an. abutment, a second laterally extending wall portion at the opposite side of the bottom portion and projecting in the same direction as the first wall portion, and a receiving groove carried by the second wall portion.

5. The combination with a window sash, of a weather strip comprising a stationary member consisting of a central bottom portion, a laterally extending wall portion at one side of the bottom portion adapted'to form an abutment and provide a tight engagement with said sash, a second laterally extending wall portion at the opposite side of the bottom portion and projecting in the same direction as the first wall portion, a receiving groove carried by the second wall portion, the opening of said groove being disposed toward the first wall portion, and r a cooperating strip member including a tongue carried by the sash and disposed in said groove when the first wall portion is en gaged by the sash to provide a double seal between the latter and the weather strip.

6. The combination with a window sash, of a weather strip comprising a stationary member consisting of a central bottom portion, a laterally extending flexible and resilient wall portion at one side of the bottom portion adapted to form an abutment and provide a tight engagement with said sash, a second laterally extending wall portion at the opposite side of the bottom portion and projecting in the same direction as the first wall portion, a receiving groove carried by I the second wall )ortion the o )enin" of said groove being disposed toward the first wall tion is engaged by the sash to provide a double seal between the latter and the weather strip.

7. The combination with a window sash having a rabbet, of a weather strip comprising a stationary member consisting of a central bottom portion, a laterally. extending flexible and resilient wall portion at one side of the bottom portion adapted to form an abutment and provide a tight engagement with one side of said rabbet, a second laterally extending wall portion at the opposite side of the bottom portion and projecting in the same direction as the first wall portion, a flange projecting from the first wall portion towardthe second wall portion and adapted to engage the other side of the rabbet, a receiving groove carried by the second wall portion, the opening of said groove being disposed toward the first wall portion, and a cooperating strip member including a tongue carried by the sash and disposed in said groove when the first wall portion is engaged by the sash to provide a double seal between the latter and the weather strip.

In testimony whereof I hereunto aifix my signature.
